Master classical homoeopath, George Vithoulkas, here describes in depth and detail for the first time, 12 different levels of health. Depending on your individual vitality, inherited miasm/s and degree of disease suppression by allopathic drugs particularly, you will fall into a particular category. Levels are related to suggested potencies as well as to prognosis. Case studies, accompanied by a discussion of the patient's response and statistical evaluation of results show how this approach works. Whether you are a serious student, practitioner, or interested dabbler in homeopathy, you will find this book of interest. Rigorous, detailed, and scientific.
